Starlight Instruments TRUE 3" Feather Touch dual speed focuser - 38 mm (1.5") travel

This True 3? Feather Touch Focuser has the same design and style that you have come to love but is over-sized to accept 3" accessories for astrophotography and visual observing.

The opening of the draw tube is 3.2" and when used with a 3" compression ring (optional), it will allow a 3" eyepiece, diagonal or any other 3" viewing accessory to be used. That is the difference to a standard 3" focuser.

The optional 2" clamping is extremely precise, tilting is not possible. Nevertheless, the focuser allows a screwed-in connection by a female thread with 86 mm diameter (M86x1).

Photographically, the focuser offers a better illumination than 2" focusers, needed for working with larger sensors or faster telescopes.

With 38 mm (1.5"), the travel range is tight, but on the other hand the focuser can be used with Newtonian telescopes, as the tube does not protrude to much into their tube.

The advantages of the Feather Touch focusers from Starlight:

100% correct position of of the image plane - no tilting or bending

good illumination also for larger sensors

gear reduction for exact focusing

free adaption to different telescope types (connection adapters can be found at the accessories recommendations)

brake for adjusting of the drag makes clamping unnecessary

adjusting and bearing are uncoupled

brass gear rack and hardened stainless steel gear wheels ensures precise adjustment even under maximum load

long life cycle - the Feather Touch focuser is made for at least the life of the telesope it is attached to

wide range of accessories and adapters available, including motorisation

Note: connection adapters to the telescope and eypiece-side adapters are not included in the scope of delivery.
